Convertible couch, settee, divan, and the like



Aug. 19, 1952 J-UNTERHALTER 2,607048 CONVERTIBLE COUCH, SETTEE, DIVAN, AND THE LIKE Filed Sept. 8, 1947 2 SHEETSSHEET 2 The movable bedstead is connected to the divan 25 in normal manner i. e. by means of a lazytongs mechanism 26.

When not in use the movable bedstead is normally stowed within the framework of the divan 25. In this position the upper frame l of the movable bedstead is supported upside down on the side rails 23 of the lower frame 3 by the supporting lugs 22 which rest on their faces 22a (Fig. 3) and. the mattress whioh is strapped 110 the frame l is suspended below lt within the frame 3 as shown in Fig. 2.

When required for use, the movable bedstead is withdrawn from the framework of the divan 25 to the position shown in Fig. 2. Foot pressure is then applied to the hell orank lever l! which raises the rails 9 through the levers 5, 5 and with it also the upper frame I which is pivotally connectecl to the rails at I0, until it reaches the position shown in Fig. 3. In this position the upper frame l is no longer supported on the lower frame 3 and is capable of being swung around the pivots l until the mattress oceupies its normal position with respect to the Sprung frame i. At this stage pressure on the hell erahk lever I7 is released and the frame i together With the mattress 2 is lowered until the faces 22b of the supporting lugs 22 come to rest on the side rails 23 in the position shown in Fig. 4.

The movable bedstead is now reacly for use and may be positioned directly alongsicle the divan to form a doublebed or separatecl from it to form a single beglby removing the pins 26a (Fig. 3).

When the moveible bedstead is no lon%er required, the operation described. above is reversed and the upper frame l and mattress 2 Will resume the position shown in Fig. 2 ready for stowing under the divan 25. y

It will be appreciated that the action of the tension springs 24 aids in the lifting of the upper sprung frame and mattress by the lever arrangement aforesaicl and only a relatively sligh t pressure on the bell crank lever ls required.

Referring now to Fig. in which parts similar to those ehown in Figs. l to 4 are designated by like numerals:

Ihe upper frame l is eccentrically mountecl at each end on a fianged wheel 21 adapted to move transversely across top end rails 28 of the lower fr ame 3 of the bedsteacl. Levers 29 (one at each end) are pivotally connected to the lower frame 3 at 30 and to the upper frame l at 31. Straps 32are fixed to the one sicle 33 of the upper Irame l and supporting lugs 34 are provided on the same side.

The upper frame I is normally supported in a horizontal position by means of the w heels 21 and the supporting lugs 34 which latter rast on the one side of the lower frame 3.

In order to bring the mattress into position either on top cf the frame l or below it within the lowerframe 3, the side 33 of the upper frame l is raised from thatside of the lower frame 3 on which the supporting lugs 34 rast, by means of the straps 32, until the frame l reaches a vertical position. Thereafter the side 33 of the frame l is lowered onto the opposite side of the :frame 3 until the lugs 34 come to rest on it.

During this process the wheels 21 Will move along the rails 28 toward the opposite side of the frame 3 and the frame l will rotate about the pivot 31 through 180. A

By virtue cf this invention, it has been made possible to lower the upper sprung frame 01 the movable bedstead and the mattress, within the lower frame to such an extent that an appreciable clearance is provided between the said upper frame and the framework of the divan within which the movable bedstead is stowed. This space can conveniently be used for stwing the bedding which has hitherto required a speoial place of safekeeping when not in use.

I claim:

1. An article of furniture of the type stated having one bedstead constituted by the normal seating area of the article of furniture and another bedstead comprising a separate frame, movable from a position in which lt is stowed away within the article of furniture into an exposed position alongside of the latter; in which the movable beclstead comprises a lower main framework; an upper mattress supporting frame to which a mattress is attachable, a pair of horizontal end rails on and between which the mattress-supporting frame is pivotally mounted; lever means for raising the horizontal end rails, and with them the mattress supporting frame, vertically from seid main framework from a position in which the mattress is suspencled downwards from its rrarne and housed in the interior of the main framework, into a position in whi0h the mattress-supporting frame may be rotated about its piVots through so that the mattress lies above and on top of its frame; and lever means for thiareafter lowering said horizontal end. rails down upon saicl main franiework.

2. An artitzle of furniture of the type stated having one bedstead constituted by the normal seating area of the article of furniture and another bedsteadcomprising a separate frame movable from a position in which it is stowed away within the article of furniture into an exposed position alongside of the latter; in which the movable beclstead comprises a lower main frame m0untecl on oastors and provicled in the bottom portion 01: each end. With a horizontal. slot;- a pair of horizontal rails each of which is provided at one end with a horizontal slot; an upper mattress-supporting frame pivotally mounted on and between the horizontal end rails; supporting lugs on the upper frame for supporting it on the sides of the lower main frame in a position where the two horizontal slots at each end of article of furniture (i. e. one in an end rail and one in the main frame) are vertically above each other; a pair of crossed levers at eaoh end or the main frame pivotally connected together where they cross each other, the lower ends of each pair of such levers being respectively pivotally connected to the main frame and pivotally mounted in a slot in such main frame, and the upper ends of each pair of levers being respectively pivotally connected to a. horizontal end rail and pivotally mounted in the slot in such end rail so that the end rails, and with them the upper frame, may be raised from and lowered onto the main frame by means of the lever system; a shaft extending from one end of the main frame to the other and mounted for rotation relative to such main frame; a bell-crank lever mounted on one end of the shaft; a link pivotally connected at one end to the bell-orank lever and at the other to the pivotal point of one pair of crossed levers; a crank lever mounted on the other end of the shaft; a linl:v conneoted at one end to the crank lever and at the other to the pivotal point 0f the other pair of crossed levers; and a coil-spring 5 disposed horizontally between the upper ends of Number each pair of crossed 1evers. 1995787 JACK UNTERHALTER. 2051959 2139923 REFERENCES CITED 5 2169175 The following references are of record in the file of this patent:
